Dr. Watters^ Doctrines of Life. Keprinted from tlie St. Louis Medical 
mid Sui'gical Journal, Nos. 3 and 4. 1868. This pamphlet relates to a con- 
troversy between Dr. W. B. Carpenter, V.P.R.S., and an American physician, 
Dr. Watters. The latter accused Dr. Carpenter of appropriating his ideas 
on the subject of the circulation of the vital and physical forces. Dr. Car- 
penter replies : My opinions were expressed in a memoir read before the 
Royal Society, and published in its ^Transactions ’ in 1850 : Dr. Watters’ were 
not published till some months after.” From what we have^ read in this 
pamphlet we do not believe Dr. Carpenter appropriated Dr. Watters’ 
opinions, and we think it a pity that the controversy should have been 
broached at all. 
The Flight of Bats, Birds, and Insects, in reference to the subject of Aerial 
Locomotion. By M. De Lucy. Translated by C. B. Fox, M.D. Scarborough. 
This interesting pamphlet has been published by the Aeronautical Society. 
It is an application of comparative physiology to the question of aerial loco- 
motion, and is most ably done. The author very carefully describes the 
different mechanical conditions on which flight in various animals depends, 
and he thus gives us the philosophical principles on which our efforts to 
construct flying machines must be based. Dr. Fox has performed his task 
of translation creditably. 
An Essay on the Geology of Cumberland and Westmoreland. By Henry 
A. Nicholson, D.Sc. M.B. London : Hardwicke. This is a graduation 
thesis, which obtained the gold medal of the University of Edinburgh in 
1867. It is a perfect monograph of one of the most interesting geological 
districts in England, and will be foimd invaluable to those who are engaged 
in trying to solve the tough problems which the geology of the locality 
offer to the philosopher. It is in gveat part based on Professor Harkness’ 
late researches, and is well illustrated. 
The Woodhall Iodine Spa, Lincolnshire. By R. Cuffe, Esq., M.R.C.S. 
London : Lewis. Waters containing iodine are often found useful in 
various scrofulous and rheumatic affections. This Spa is singularly rich 
in iodine, and may be visited by certain invalids with advantage. 
The Scientific Exploration of Central Australia. By Dr. Gr. Neiimayer. 
From Proceedings of Royal Society, No. 102. Dr. Neiimayer points out 
clearly what may be effected by further exploration, and how exploring 
parties should be furnished and conducted, in order to obtain the best prac- 
tical and scientific results. 
Musical and Sensitive Flames. By W. F. Barrett. A reprint from the

journals.
